Dear Sir or Madam,

I am writing to apply for the top up studies of management in hospitality in University of Central Lancashire starting September 2012. My goal is to learn more about hotel management, i am also planing work while studying so that i can master my hotel management skills.
To be fair I did not choose this career because it was a dream of my life, i chose it because i thought it would be fun to learn about hotels and tourism, and only half way through my course i realized that i realy would like to make it my carrer. As i graduated from collage i got myself a job i a hotel as a porter, that was my first actual introduction to a hotel. After a while i knew that this is the field i want to work and have a sucessfull career in. Since then i have worked in several hotels, now i am working as a front office clerk. Over the time i worked in those hotels is saw several different ways of managing a hotel, i now have an opinion on how i could manage a hotel when i become a manager, however i also realised that i still have a lack of education and practice for this job.
I never was amongst top students in my college nor school, however i have a passion for hotels therefore i am ready to give my best to suceed in graduating from your university and achieving succesfull career.
The main reason why i want to pursue a career in hotel industry is that i am facinated by its discipline and etiquette regarding the clients of a hotel, its set of rules and regulations that creates an ideal system wich holds the entire bussiness together and the unique team work that brings together every member of the staff for the same purpose – to create a home for each individual seperatly considering their needs and requests.
I chose University of Central Lancashire because i think this particular course best fits to my goals, i also did a little research, viewed a lot of reviews and coments and i realy think i would fit in perfectly in your little comunity.
In conclusion I would like to say that I like to take responsibility and to work as part of a team. I am eager to gain new experiences and in my opinionthis program is the best way to achieve that. I am positive that the University of Central Lancashire would be an excellent start for an ambitious hospitality career.

Thank you for considering my application.

Sincerely yours
